A bind mount works like mounting any other hard drive.  Everything below 
the place that you mount the filesystem gets replaced by the drive you 
mount on top of it.  If your filesystem were a tree it would be like 
cutting off a limb and grafting a new limb onto where you cut it off.
There is a way to layer up directories, it's call a Union filesystem and 
allows you to merge directories together, but they are a little harder 
to setup that just a simple mount.

the ~ means "home directory of", if you have just a ~ by itself it will 
refer to the home directory of the current user, if you put a ~ in front 
of a user name, it means the home directory of that user.
Since you were most likely mounting stuff as root, you needed to include 
the user name after the ~, otherwise you could have simply put ~/Pictures.
In your case if you were to have put ~/bmike1/Pictures, as root it would 
actually turn into the path /root/bmike1/Pictures or if you had run the 
command as bmike1 it would have really meant /home/bmike1/bmike1/pictures
